HEEL-IBREASTING MACHINE.

Application filed July 1, 1918, Serial No. 242,764. Renewed December 28, 1922.

To all whomy it may concern.'

Be it known that I, ELMER B. GRUsH, a citizen Aof the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Heel-Breasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for opcrating upon heels, particularly Louis heels, and is herein shown and described as rembodied in a machine for forming the breast faces of Louis heels.

The formation of a modern Louis heel, as usually performed by prior machines, involves generally three operations, viz., iirst the shaping of the heel longitudinally, that is, lengthwise of the shoe, in the form of a curve, this curve being concave relatively to the heel and varying in curvature from substantially nothing at the tread face to a curve of short radius adjacent to the shank of the shoe; second, the shaping of the base or seat portion of the heel breast which eX- tends along the shoe shank, to the transverse convex curvature of the shank of the sole at this point; and third, the forming of the portion of the breast face adjacent to the tread face of the heel with a transverse con- Ycavity or scallop, this concavity being formed in that portion of the breast next to the tread face .including the portion which has little or no longitudinal curvature. is further desirable that the intermediate portion of the breast between the shank portion and the scalloped portion be concaved laterally of the heel. The surfaces or portions of the breast surface abovementioned preferably are caused to merge into .each

V other to form a breast of compound curvature without sharp lines of demarcation between the portions of diierent curvature and particularly between the scalloped portion and the intermediate portion. j

An object of this invention is to provide a machine by which the breast face of a Louis heel may be completely formed with portions of different curvature and by which the various portions of different curvature may be caused to merge into each other without lines of demarcation appearing between them.

A further obj ect of the invention is toprovide mechanism for hblding a heel, and preferably a shoe with a heel attached thereto, in predetermined relation to a cutter of suitable shape and to provide such relative movement between the heel and the cutter that the various surfaces above mentioned may be formed upon the heel by operation upon the heel of the same cutter and while the heel or shoe is held in clamped position. The organization of the machine preferably includes a novel rotary cutter of the type which, when in rotation, traces a body which in longitudinal cross section has a curve corresponding substantially to the longitudinal curve of a Louis heel. In accordance with this invention, the curve of the cutter which varies in transverse section has portions corresponding in curvature to the transverse curve or concavity usually formed in the breast face of a Louis heel adjacent to the tread face thereof. As shown, the cutter is substantially egg-shaped or pear-shaped with reference to the shape traced by its cutting edges when in rotation, and is designed to eifect cutting operations upon the work when the work is presented to its larger end which may be substantially hemispherical in shape and also when pre-V sented to its side portions. A cutter of this shape is not claimed herein but is disclosed. and claimed in a copendting application., Serial 241,393 iiled June 22, 1918 by H. M. Loomer. The illustrated cutter, however, comprises a plurality of blades which are secured to the faces of a pyramidal core or carrier and the carrier is held to the cutter shaft by means of an expanding mandrel.

Very important features of the invention consist in an organization comprising means for holding a heel or a shoe with the heel attached and a cutter which may be of the form above described mounted for rotation about an axis substantially perpendicular to the tread face of the heel together with means for moving relatively the shoe holder and the cutter to effect the desired formation of each of the above described portions of the breast surface.

One such feature of the invention consists in means for effecting a lateral movement of the cutter relatively to the heel whereby the heel is trimmed to a longitudinal curve corresponding to the curve of the cutter on a section taken in the direction of its axis. 'Preferably Vthecutter is moved bodily about an axis of relatively large radius which, however, gives a substantial transverseconcavity to the heel breast. This axis may, as herein shown, be located below the heel yand in a direction substantially parallel with the portion of the shoe sole between the shank and the ball of the shoe.

Another of these features of the invention consists in means for automatically effecting Arelative movement `between the cutter and the shoe support. or holder to cause the cutter to tra-verse the heel breast. The arrangement is such that the relative transverse movement may be varied and preferably is progressively variable at the will of the operator. In "the organization herein shown, the cutter is swung repeatedly and automatically 'to and fro across the heelbreast and manually operated means is provided for controlling the extent of the swingingv movement of rthe cutter and to cause such movement to diminish or to cease when desired.

Still another suchv feature of the invention consists in an organization by which movement of the cutter is eected to cause the cutter to trim the vheel at the base of the heel to the transverse convex curve of the shank ofthe shoe. As herein shown, the cutter is Vmounted for movement about an axis extending ltransversely of the shoe, and means is-provided for controlling movement. of the cutter about this axis inthe direction of the height of the-heel to cause the cutter to followthe convex curvature of the shank and to trim the 'base of the heel on a curve merging into the curve of the shank over which the base of the'heel extends and into the 'curve ofthe breast above the 'shank'po'rtion when the cutter is moved to cause lateral transverse movement of the heel and cutter, as above described. As herein shown, a changeable cam is provided to control movement of the cutter perpendicularly to the shank, which cam has a curvature corresponding to the curve of the shank of the shoe being treated.

A further feature contributingito the 'formation-of the heel breast consists in an organization for causing relative movement of the heel and cutter in the direction of the height of the heel to effect concaving or scalloping of the portion of the breast next to the tread face of the heel. As herein shown,

the shoeis held in fixed position and means is provided for moving the cutter vertically of the heel and substantially in the direction of the axis of the .cutter'to effect the scalloping operation.

In accordance with one of the objects of the invention, the means for controlling the automatically effective transverse movement of the cutter is'correlatedwith the means for effecting movement of the cutter in the direction of its axis so that the transverse movements are caused gradually to cease in conjunction with the movement of the cutter in the direction of its axis to effect the scalloping operation. By this organization all sharp lines of demarcation between the surface formed by the transverse movement of the cutter and the surface formed in the portion of the heel breast near the top lift by the movement ofthe cutter in the direction of its axis are eliminated and by the time the cutter has moved in the direction of its axis suciently to bring the portion of the cutter having the largest radius yof curvature opposite the edge of 'the top lift, the transverse movements ofthe cutter have entirely ceased and the concavity in the breast face next to the top llift is formed solely by movement of the rotating cutter in the direction of its axis and of a curvature corresponding to the largest radius of the cutter.

Another vfeature of the invention consists in an organization including a rotary cutter constructed and arranged to be moved bodily transversely of the heel while in rotation and a shoe support adapted to hold a shoe in clamped position vand arranged for movement toward and from thel cutter.v As shown herein, the cutter is arranged for bodily movement about an axis which is parallel to the direction of movement of the shoe support toward 4and from the cutter. This organization enables the support to be advanced gradually toward the cutter while the heel is` treated by repeated transverse movement of the cutter.

A further feature of the invention fco'nsists in an organization including means for clamping a'shoe and a cutter having an end cuttingportion of curved contour arranged for rotation' about an axis substantially perpendicular to the top lift of the clamped shoe and amounting for the shoe holding means which permits movement of the shoe about a center located substantially at the center of curved contour of the cutter. Preferably adjustable means is provided to limit movement of the clamping means about said center.

An additional feature of the invention consists' in an organization including shoe holding means and an egg or pear-shaped rotary cutter mounted for rotation about an axis substantially perpendicular'to the tread face of a shoe vin the holding means with manual means for moving the shoe holder toward the cutter in a direction substantially parallel with the shank portion of the shoe between the heel Yand ball, the shoe holder being also mounted for rotation about a center located substantially at'the center of cur- CSI vature of the end of the pear-shaped cutter. By this organization the shoe holder may be moved about the last mentioned axis to cause the portions of the cutter of less curvature to treat a portion of the heel breast adjacent to its top lift and form thereon a concavity without edecting the treatment of lother portions of the heel breast by the cutter.

These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims. In the drawings,-

Fig. 6 is a sectional View on the line 6 6 of Fig. 5.

Referring to Fig. 1 of the drawings, the numeral 2 indicates the frame of the machine head which is preferably mounted on a column 4. Running longitudinally through the frame 2 from front to rear is a rock shaft 6. Outside the shaft 6 is a stationary hollow member or sleeve 8 which is mounted at its ends in openings in parts 10, 12 of the frame 2. At the ends of the sleeve 8, between it and the shaft 6, are bushings 14, 16 forming bearings for the shaft 6. Outside the member 8 is a sleeve 18 on one end of which is an eccentric 20 carrying an eccentric strap 22 for a purpose to be described, and at the other end of which a. gear 24 is secured by a set screw. Outside the sleeve 18 is a sleeve 28 on one end yof which is a driving pulley and on the opposite end of which is a pinion 32 keyed' to the sleeve 28 at 34. The pinion 32 meshes with a large gear 36 having fixed thereto a pinion 38, both gear 36 and pinion 38 being mounted on a stud shaft 40. The pinion 38 meshes with the gear 24 on the sleeve 18 carrying the eccentric 20. This construction affords a speed reduction between the pulley 30 and the eccentric 20. A loose pulley 42 having a bushing 43 is mounted loosely on' extends over two idlers 52 which are loosely. mounted 'on a shaft 54 in a member 56 which has a bushed bearing 58 for the spindle 50. The member 56fis bifurcated to receive the sleeve member 8 and a member 60 bushed at 61 on the sleeve member 8 to which member the member 56 is pivoted at 62 in line with the center of the shaft 6. This construction is best shown in Fig. 2. Downward movement of the spindle carrying end of the member 56 is limited by a projection 57 which contacts with a portion 63 of the member 60 and is normally maintained in Contact by a spring 64 mounted between an upward projection 65 of the member 60 and the member 56 (Fig. 1). It will be seen that the member 56 is capable of two movements, one about the pivot 62 whereby the spindle 50 is moved in a vertical plane extending lengthwise of the machine and substantially perpendicular to the tread face of the heel and to the shank and the other about the center of the shaft 6 as an axis whereby the spindle 50 is moved transversely of the machine and the shoe and further that these movements may be effected withoutl disturbing the operative relation of the pulley 48 to the pulley 44 through the belt 46, the spindle 50 being continuously7 driven notwithstanding these movements.

The movement of the member 56 about the pivot 62 is controlled from a treadle T0 held raised by a spring 72 and having at the rear of its pivot 74 a rod 7 6 connecting to an arm 7 8 fixed on the rear end of the shaft 6. The forward end of the shaft 6 carries an arm 7 9 having a flange 80 which is adapted to engage a roll 82 on the member 56. Movement of the member 56 is limited yby contact of a stop 84 with the projection 65 of the member 60. The stop comprises a rod 84 threaded through a portion of the member 56 and provided with a thumb head 86 by which it may be turned.

The movement of thev member 56 about the axis of the shaft 6 is effected by mechanism already partly described. The eccentric 20 has its strap 22 connected, as shown in Fig. 2, to the lower end of a grooved link member 90. The upper end of the link 90 is pivoted at 92 to a projecting arm 04 from the stationarv sleeve member 8. The link 90, therefore, will have its lower end swung to and fro at a slow rate by the eccentric 20 while its upper end is stationary. Lying in the groove of the link 90 is a roll 100 mounted on one side 'of a curved link 102, Fig. 3. Opposite the roll 100 is another roll 104 which engages a groove in the rearwardly bent end of the arm 7 9. This groove is curved from the pivot 92 of the link 90 as a center. Obviously, when the sha-ft 6, to which the arm 7, is fixed, is rocked by the treadle the roll 100 will be moved up and down in the groove of the link-90 and consequently more or less movement Vwill be communicated to the link 102. The link 102 has its opposite end pivoted at 103 to a curved lever 106 fulcrumed at 108 to a lug 109 on the arm 94 of the stationary sleeve member 8. The lower end of the lever 106 is forked to embrace a roll 110 on the downwardly projecting end 63 of the Vmember 60. Oscillation of the link 90 communicated through the link 102 to the lever 106 will, therefore, cause the member 60 to be rocked about the axis of the shaft 6 and with it, of course, will m'ovethe member 56 and the spindle 50.

The spindle is hollow and through it extends a rod 120 which has a head 124 pinned to its upper end by which it may be turned. The lower end of the rod 120 is threaded into a tapered nut 121 which engages a similar formation in the end of the spindle 50 which is split at 51 toY permit expansion of it by the nut 121. The end of the spindle 50 is adapted to enter when contracted a hole 53 in the body portion 123 of the cutter designated in general by the numeral 122. The portion 123 is a square pyramid in shape, and to each of `its sides is secured a cutter blade 125 by means of dowel pins 127 and a nut 129. The shape and arrangement of the cutters is clearly shown in Figs. 5 and 6. By placing the cutter 122 upon the end of the spindle 50 and turning the head 124, the spindle is expanded to hold the cutter upon the spindle. In referring to the cutter as pear-shaped, reference is made, of course,'to the shape traced in space by the cutting edges when the cutter is in rot-ation. This shape comprises an end portion of substantially hemi-l spherical shape and side portions of less curvature.

The work support will now be described. Extending horizontally from the machine frame are two members 130, 132 on the innen faces of which guideways 1-34 are formed. Arranged to slide in the ways are rectangular portions 136 of a U-shaped member 137 which depends between them. Above the rectangular portions 136 are ears 138 to each of which is pivoted atf139 apart 140, the parts 140 being connectedfby a plate 142 extending between them and against which the tread face 'of the heel of a shoe is presented. To position the heel longitudinally, a plate 144 is provided which has a V-shaped notch to receive the rearend of the heel and is adjustably held to theV plate 142 by a thumb screw 146. To clamp the shoe against the plate 142 -a U-shaped member 150 is provided which embraces the shoe and has its ends pivoted to the parts 140 at 141. Movement of the member 150 about the pivots 141 is limited in one direction by the plate 142 (see dotted lines Fig. 4) and in the other by lugs 152 on the members 140, In the bight of the U-shaped member 150 is a recess containingV a nut 154 having an operating handle 155 and,

threaded by coarse threads tov a sleeve 156 which Vpasses freely through the member 150. Extending through the sleeve 156 is a rod 160 having aV head 162 at one end to engage the last and at the other a knob 164 by which the head 162 is pushed into Vengagement with Vthe last. A pawl 166 is pivoted between ears 168 on the sleeve 156 and 'is normally held by a leaf spring-169 l(Fig. 1) in engagement with teeth 170 on the rod 160, the teeth being arranged vto prevent movement of the rod away from the last. The pawl 166 has a thumb piece 167 by which it may be readily released.r After the rod 160 has been pushed against the last and is held in that position by the pawl 166, the nut 154 is operated by the handle 155 to move the sleeve 156 toward the last and therefore cause the pawl to move the Yrod 160 further forcibly to press the head 162 against the last to clamp the tread of the heel against the plate 142. Outside the nut 154 a cap piece 174 is secured at 175 to the member 150. VThis forms an abutment for the nut 154 and has a slot 17 6l to receive 'the ears 168 to which the pawl 166A is pivoted and prevent rotation of the sleeve 156. The spring 169 is conveniently anchored to the cap piece 174, the relative movement between this and the pawl release 167 being insufficient to disturb thefoperative relation of the spring.

After being clamped as described, the shoe and shoe holding means (142, 162) are free to move about the pivot 139 to the position shown in Fig. 1 where a lug 180 on the parts 140 comes into engagement with -an adjustable stop screw 182 shown as a screw threaded through a projection 184 from the ear 138 on the member 137. 'On the screw 182 `is a s'et nut having an operating handle 186 to hold the screw from rotation. Adjustment of the screw 182 varies the position of the shoe about the axis of the 'pivot 139 which, when the shoe is in operative 'relation to the cutter, passes through the cutter approx-imately at the center of curvature lof its rounded end.

The shoe positioning and holding means, when positioned as described, may slide to carry the shoe toward and from the cutter in a horizontal direction on the guideways 134. It is important that this movement, as the shoe approaches thecutter, Vbe under delicate and positive control by the operator. For this purpose teeth 190 are formed in the lower edge of vone of the rectangular portions 136 of the member 137 which teeth are engaged by a pinion 192 on a shaft 194 journaled in the horizontally extending member 130. On the outer end of the shaft 194 is a handwheel 196 by which the pinionr 192'may be rotated to move the shoe holding means toward and from the out ter 122.

When the machine isin operation, it will be understood that the cutter shaft 50 will be rotated at high speed from the pulley 44e, that, through the reducing gearing described, the eccentric 20 will be rotated at low speed, that the eccentric strap 22 will cause the link 90 to swing on the center 92, and that the motion of the link 90 will be communicated through the link 102 to the lever 106 which will be swung to communicate the swinging movement to the cutter head 56 and will cause maximum swinging movement thereof laterally of the heel. The operator places a shoe having a last therein with the tread face of its heel restin'g against the plate 142, the longitudinal position of the heel being determined by the adjustable plate 144 which engages the rear end of the heel. He then pushes the plunger 160 against the last, where it is held by the pawl 166, and operates the handle 155 to complete the clamping of the shoe. IIhis clamping of the shoe may be done while the plate 142 is in the position shown in Fig. 4, the shoe being positioned as sho-wn and the clamp being swung from the dotted line position to the full line position of that igure. The shoe and its clamp are then swung about the center 139 into the position shown in Fig. 1 and the shoe and clamp are pushed bodily toward the cutter 122. As the shoe approaches the cutter, the pinion 192 engages the teeth 190 on the slide 136 and the advance of the shoe toward the cutter may then be delicately controlled by manipulating the hand wheel 196.- As the cutter swin'gs across the heel breast, the central portion of the breast is trimmed to a longitudinal concave curve corresponding to the curve of the side portion of the cutter and is trimmed, also to a transverse curve by reason of the movement of the cutter in a circular are about the axis of the shaft 6. At the same time the end portion of the cutter is caused to follow the convex curve of the shank by reason of its movement about the same axis 6 which lies substantially parallel with the portion of the shank between the breast of the heel and the ball of the shoe. T his movement, however, is modified by contact of a roll 198 on the head 56 with a cam 20() fixed to the frame 130 of the work support. The cam 200 is designed to eifect a slight movement of the head 56 about its transverse axis 62 to cause the lateral traverse of the end of the cutter to correspond accurately with the curve of the shank, different cams being provided to take care of different styles or curvatures of the Shanks. After these operations have been effected, the treadle is actuated to cause swinging movement of the cutter to cease and to effect movement of the cutter substantially in the direction of its axis about the center 62 to effect the scalloping operation upon the heel. This movement of the cutter in the direction of its axis while the lateral movements are gradually ceasing c :auses the breast portion of the heel adjacent to the top lift to be given a transverse curvature or scallop corresponding to that of the cutter at its largest radius and this scalloped portion merges into the adjacent surface of the heel having a curvature of larger radius determined by the movement of the cutter about the axis 6.

If a scallop of smaller curature is desired, as for instance, upon a heel having a small top lift, the heel may be moved away from the cutter before the cutter is raised and the top portion of the breast again presented to a portion of the cutter nearer its end and having, therefore, a smaller radius of curvature. The stop 811 may be used to limit movement of the cutter and secure imiformity of work when the tread portion ofthe breast is presented for the scalloping operation, as described, to portions of the cutter below its largest diameter.
